Subject:      Engine Disassembly, EGR, Air Pump

Tthe engine (1973 1700 Type IV) is out of the bus to be overhauled over the winter. After an afternoon of mild exertion, the motor is sitting on a workmate in my basement. I have a few questions...

Some of the tin is very rough (rusty). In fact, it is a real mother getting the screws out (screwdriver ...nope... vise grips ...nope... chisel...nope... drill). What is recommended for cleaning up old engine tin?

Not to my suprise, the air pump is frozen solid and the EGR is all clogged up. Disposing of the air pump and associated equipment appears trivial, but I am not sure how the EGR system is attached to the heads. A pretty wimpy peice of pipe sticks out of each head near the intake port. Is it possible to remove this and plug the hole? I expect that a motor tuned to run without the aforementioned pollution controls will pollute less than with non-functioning pollution controls attached.

I have seen big-bore cylinders advertised for the 1700 (96mm vs 90mm) are these an easy swap, and would there be a noticeable increase in power without replacing the stock Solex's or exhaust?
